If you’ve been on TikTok in the last few weeks, you might have seen that American women are talking about 4B. The South Korean feminist movement gets its name from the “Four Nos” its adherents commit to: no dating, no sex, no marriage, no childbirth. In short, 4B, which began around 2019, encourages women to actively avoid men as much as possible. That it’s now trending in the U.S. raises an uncomfortable question: Are our gender politics starting to look like Korea’s? And if so, will the demographic consequences be as extreme?
Right now, South Korea is running out of kids. Last week, it was reported that the Education Ministry plans to reduce the number of teacher training places, citing the precipitous decline in students, which is so extreme that in March of this year more than 150 schools across the nation had no new first graders. Six years ago, the average number of children a South Korean woman had in her lifetime was 0.92, a figure rarely seen outside wartime; since then, it’s fallen all the way to 0.78, with a projection of 0.65 in 2025. In Seoul, the capital, it’s already at 0.59.
When I visited Seoul in 2022 to report on why Koreans aren’t having babies, I often found myself wondering: Could this happen in America? Our nation’s fertility, though significantly below the replacement rate of 2.1, is currently higher, at 1.8. But, in the course of dozens of conversations with Koreans of reproductive age, I heard more extreme versions of sentiments I’d started to observe at home.
Today, Americans who want a good old-fashioned heterosexual relationship struggle to find someone who shares their values. Analysis has shown a gigantic mismatch in the nation’s dating pool: for each single liberal woman, there exist 0.6 single liberal young men. Conservative young men have it even worse, with just 0.5 single conservative young women available to choose from. At the end of last year, the pollster Dan Cox found that this divide is particularly intense among American members of Gen Z, whose oldest members are now 27, the average age of a first-time mother in 2022.
In Gen Z, Cox showed, women and men are much further apart on fundamental questions of gender equality than the generation before them: whereas 52 percent of millennial men say they’re feminists, compared to 54 percent of women, the equivalent figures for Gen Z are 43 percent and 61 percent. In 2019, a third of adult men under 30 said they face discrimination based on their sex; only five years later, that number has increased to almost half.
Recent data suggest this gender divide is global—and growing. In January, a Financial Times report showed the wide, and widening, divergence in political values between young women and men. This is true in South Korea and the U.S. but also in China, Germany, and the UK.
Americans haven’t given up on having a family to the extent that South Koreans have. In 2023, about 35 percent of Koreans said they don’t think having children after marriage is necessary, a figure that rose to more than 57 percent among 19- to 24-year-olds. By contrast, a recent Gallup poll found that the vast majority of Americans under 30 “either already have children (21 percent) or hope to someday (63 percent).”
But young American women haven’t just been making TikToks about 4B out of curiosity—an increasing number are genuinely swearing off male partners, with the hashtag #celibacyjourney racking up tens of millions of views. A New York Times op-ed published in February described going “boysober” as “this year’s hottest mental health craze.” Meanwhile, men who identify as “involuntarily celibate” are retreating to online echo chambers that, one 2022 study suggested, now harbor eight times as many instances of degrading language toward women than they did in 2016. In the twelve months after December 2022, self-described misogynist Andrew Tate’s following on X increased from 3 million to 8.5 million.
Conservative politicians across the globe are capitalizing on these divides. Not long before I arrived in Korea, the president Yoon Suk-yeol had coasted into office in May 2022 on a wave of anti-feminist campaign promises, in what multiple observers described as an “incel election.” For the first time, young men describing themselves as anti-feminist were seen as an influential voting bloc, with Yoon promising to abolish the nation’s Ministry of Gender Equality and Family. (He has not yet succeeded.)
In the U.S., the Republicans also appear to be aggressively courting the male vote. Since the fall of Roe, the Republican Party has become actively hostile to women’s reproductive rights, pushing female voters left. And some of the party’s most influential members are now stoking a war between men and women.
In a breathtakingly offensive comment last January, Florida congressman Matt Gaetz called for the Republican Party to all but forget about female voters, saying that “For every Karen we lose, there’s a Julio and a Jamal ready to sign up for the MAGA movement.” Fox News host Jesse Watters has been even more explicit in singling out liberal single women as the GOP’s nemesis, alighting, somehow, on matrimony as an electoral strategy.
“Single women are breaking for Democrats by 30 points,” he said after the 2022 midterms. “We need these ladies to get married,” he warned, following up with an order: “Guys, go put a ring on it.”
And yet a recent poll found that 40 percent of Republicans said they don’t believe marital rape should definitely or probably be prosecuted, suggesting the party’s not overflowing with eligible bachelors.
All signs point to an ever-widening rift between the sexes. And if women and men become sworn enemies, America is going to start running out of kids, too.
